The Republic of Korea has awarded a contract to Telephonics Corporation for the integration of the company’s AN/UPX-44 Identification Friend or Foe (IFF) transponder onto undisclosed ground-based air surveillance radars operated by the country.

The AN/UPX-44 can work with the United States’ Next Generation Air Transportation System’s Automatic Dependent Surveillance Broadcast (ADS-B) air traffic management architecture, along with Mark XIIA IFF Mode-5 and Mode-S military and civilian transponders.

There is no word regarding which radars will be equipped with the AN/UPX-44 IFF, the value of the contract, how many systems will be delivered or when deliveries will commence and complete.
